摘要：
MgB2 wires were manufactured by the in situ technique, diffusing Mg to B particles, resulting MgB2 with hexagonal structure, after cold deformation. A comparative study of the intergranular current and grain conductivity was conducted by transport and magnetic susceptibility measurements, in magnetic field up to 7 T to define the J(c mag) and the direct current J(c) at 4.2 K, which revealed systematic differences in the flux pinning of the wires.
